BELL EINGEB.

Applicationfiled October 25, 1919.

To all whom it may concern:

Be it known that I, LnNwoon MCCLEARY, a citizen of the United Qtates, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bell Ringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to hell ringers and the primary object is to provide an improved bell ringer for locomotives, which is automatic in operation and which will eliminate any possibility of the bell turning over, and thus overcome the danger from such source at railroadcrossings. v

I Another object of the invention is to provide an improved locomotive bell ringer embodying a fluid operated piston operatively connected with the ordinary bell crank and 1 means for automatically cutting off the fluidv pressure to the piston when the same has reached a predetermined point.

-A further object of the invention is to provide an improved means for adjusting the valve cut off, so that the fluid pressure can becutofi from the piston at any point desired. I

rr still further object of the inventlon is to provide an improved locomotive. bell ringer of the above character which is capable of attachment to practically all locomotives and will operate in a smooth-and dependable manner, which is durable and efficient in .use,.one that is simple and easy to manufacture .and one which can be placed upon the market ata reasonable figure.

With these and otherobjects in viewthe .invention consists in the novelconstruction,

arrangement and formation of parts, to be hereinafter. more specifically. defined and claimed, in connection with accompanying drawings, forming a part thereof in which:

Figure 1 is a longitudinal section of the improved bell ringer.

Figure 2 is a fragmentary side elevation of the upper end of the piston rod and cou pling head, showing the means for pivotally securing the same together.

Figure 3 is a detail cross section taken on line 1-2 of Figure 1.

Figure i is a detail fragmentary vertical section through the bell crank engaging member and coupling head.

Serial No. 333,252.

Figure 5 is a fragmentary elevation of .the bell crank engaging member.

Referring to the drawings whereinsimilar reference characters designate corresponding parts throughoutthe several views, the letter"A designates a cylinder having an inverted cup shaped piston B reciprocally mounted therein, which is providedwith the piston rings a so as to form a fluid tight oint betweenthe inner walls of the cylinder and the piston. The cylinder A is provided with a lateral integral extension a which is provided with a vertical. bore a for the reception of the valve plunger C which is re ciprocally mounted therein. The valve plunger G adjacent its lower end is provided with an annular groove 1) which is adapted to be brought into and out of alignment with the ports 0 which communicate with the lower end of the cylinder and the inlet nipple n. The inlet nipple a is internally threaded and is adapted to receive a suitable connection so as to couple the same with the air or steam pipe. The admission of air or steam is controlled by a suitable valve which is positioned adjacent to the engineer, so that the engineer can conveniently open or close the same when necessary. The valve plunger C is provided adjacent its upper end with an annular flange C which engages a cushioning spring d which is coiled around the valve plunger C and engages the upper end ofthe annular extension a; Thespring opening which slidably receives the piston rod D, which is formed integral with the piston B.

The upper end of the piston rod D has pivotally connected thereto the coupling. head F, the lower end of which is bifur- I cated to receive the reduced end of the pis-- ton rod. The reduced end 03 of the piston rod and the bifurcated portion of the coupling head F are provided with aligned openings which receive a coupling or pivot pin G one end of which is provided with a head 9. The opposite end of the coupling or pivot pin receives the sleeve h and is en gaged by the cotter pin 9, which extends through the coupling pin G. The coupling pin G adjacent the head 9 is slightly enlarged in diameterand receives the upper end of a connecting link E which has its lower end bent outwardly and "downwardly in close proximity to the valve plunger (3.;

The lower end of the connecting link carries the outwardly extending foot 6 which slidably receives'the slotted upper terminal oftthe valve plunger 0. The outer end of the foot is-providedwitha largehead p01 and engages the outer surface of the cpluirger valve C; The upper terminal of the "plunger valve C-is provided with the adjustingvscrew e which is held i1r adjusted ipositio lr bymeans of the lock'nut f the pur- LPOSQOfWliiCll will be hereinafter more fully described.

Theupperterminal'ot the coupling head F receives the "externally threaded rod H which is also fitted into'the threaded bore of,the bell:crankengaging member I. The u'pper end of which is slotted to receive the o'uter terminal of thebell crank 11.. The

bell crank of the ordinary construction, and is -attached to f the ordinary locomotive b'ell i'n-the usual manner.

The bell crank engaging member Iis connectedl'to the coupling head F by the threadi ed rod H, so that the same can be adjusted in re1ation'to the piston and cylinder so as -to beattached to a' larger or smaller bell and the sameis 'held inposition by a lock I In the operation of the, improveddevice,

the fluid under pressure enters through the mpple and flows around the annular e groove b throughthe portsc andinto the cylinder A a'ndunder the piston D andiforces the During the raisgroov'ed" portion thereof above the ports 0 and thus cuts oil further supply of fluid '1 to the cylinder.- The wall of the, cylinder A is provided with an exhaustfport Z which is adapted to register with an exhaust port mprovid'e'd'i'n the wall of the cylinder so Witnesses that when thepiston raises, the fluid pressure will be released and the weight of the bell crank causes the return of the piston to its-lowered position carrying the plunger valve C therewith, and the grooved portion thereof into alignment with the ports 0 which again ringsthe bell. i i

It will be seenthat through the medium of the spring d the lowering movement; of

the plunger valveC will be cushioned; 1 The i lower end of the cylinder is provided with aremovable threaded plug -K, so that-the cylinder can be cleanedwhen'necessary; I In practice, I have found thatthefoiin of my invention illustrated in the accom- I panying drawings; and referred to in the above description, as the preferred embodiment,'-is the most efiicient andpractical;

yet realizing the conditions concurrent with d e-adoption 'ottmydevice will necessarily vary, I; desire to emphasize that various minor changes in details of'constru-ction, proportion and arrangement of. parts be resorted to, when requiredwitho-ut sacrilicing any of the advantagesof my' invention as set forth.
